KNOCKDOWN SUPPORT.

Application filed April 19, 1923. Serial No. 633,299.

' clamping members, one pair of which is intended to engage and hold the legs and the other pair to engage and hold a series of lateral bars on which the object to be supported will rest.

The entire set of four clamping members are held together by means of a single bolt, centrally disposed, so that the loosening of the nut on said bolt will permit the removal of the legs and the arms, to the end shipping, and easily and quickly assembled and set up for use.

The invention is more fully described in the following specification and clearly il lustrated in the accompanying drawing, in

which Figure 1 is a plan view and Figure 2 a side elevational view of my device, assembled.

Figure 3 is an enlarged plan view thereof, with the arms and legs broken away, and Figure tis a central sectional view taken through line 3-3 of Figure 3.

The numeral 1 designates the lower, and 2 the upper member of the leg clamp. These members are each formed with a series, preferably three, of half round, downwardly projecting jaws 8, each pair of jaws forming a receptacle for the inner end of one of the legs 4.

The numeral 5 designates the lower, and 6 the upper member of the arm clamp. These members are each formed with a series of radiating grooves 7, and engaging these grooves, between the upper and lower clamp member, is the inner end of one of the supporting arms 8.

Each member of the two clamping sets, 1, 2, 5 and 6, is provided with a central opening and a bolt 9 passes through the that the device may be easily packed for openings, has its head embedded in a depression 12 in the upper surface of the member 6, to form a flush upper surface therefor, and a nut 13 on its lower extremity, whereby, the tightening of the nut on the bolt will draw the members 1, 2, 5 and 6 together, and effectively secure both the series of leg members 1 and the arms 8 in position.

he upper edge of the leg clamp member 2 is formed with a series of slight depressions 11, in each of which one of the radiating grooved portions 7 of the clamp member 5 will rest, and, when the parts are drawn together as above described, this will prevent rotation as between the arm clamp and the leg clamp members.

It is evident that a very slight loosening of the nut'l3 will permit both the leg and arm clamping members to open sutliciently to allow the withdrawal of the legs and arms, and permit a compact parcel to be made of the entire device.

It is also evident that the support may be used for other purposes than that of supporting a washing machine. tub, and that the number of legs and arms may be varied to suit circumstances.

Having thus fully described my iuvention, what I claim is r.

1. In a knockdown support, a pair of leg clamping members provided with leg engaging jaws, a pair of arm clamping members provided with arm engaging grooves, each member having a central opening, a series of depressions in one of the leg clamping members adapted for engagement by one of the arm clamping members and a single bolt passing through the central openings and capable of securing the leg and arm clamping members together.

2. In a device of the character described, a two-piece leg clamp provided with leg openings, a two-piece arm clamp provided with arm engaging means, depressions in one of the leg clamping members adapted for engagement by one of the arm clamping members to prevent independent rotation, and a single bolt capable of drawing both the leg and the arm clamping members together.

In testimony whereof I aflix my signature.

CALVIN J AGKSON.
